Looks like ballpark 3-4 degrees off for PSM. That always seems to be the biggest model bias...it is too diffuse with the CF...instead of keeping it right on the coastline or even just offshore in this case, the guidance makes it this diffuse thing that spreads west over way too large of an area rather than tightening up that gradient. And of course, they often aren't far enough south with the CAD drain. Link to comment Share on other sites More sharing options...

The 4 Seasons Posted January 20, 2019 Share Posted January 20, 2019 The Snow/Mix line is moving through the state rapidly. Looks like most towns will see 2-4" maybe 5 or 6" counting the sleet, but i doubt we see anything over that. Link to comment Share on other sites More sharing options...

And of course, they often aren't far enough south with the CAD drain. It's definitely almost always too far west, but it also does a weird dual structure at times. Like really cold on the poleward side of the sharpest gradient, then some diffuse middle ground between the teens and 32, then the above freezing air.

Typical Road salt becomes almost totally useless around -5F. But once youre below 10F, it is struggling...it just gets less ad less effective as you get lower, and once youre well into negative numbers, it's pretty bad.

Think I might end up on the other side of the CF tho Yeah Boston itself will be too far east....we will have to watch closely in the morning though if mesolow forms then it could slosh into the city. But for now, the drain is moving away from the shoreline in MA. It looks like it is having trouble penetrating east of 95 in Essex county. But not far west of BOS near 128 could get it.
